HYDROMETER CUP ANDTHIEF.

' Application filed November 15 1882. (No model.)

To aZZ whom it may concern:

Be it known that I, JACOB DAVID, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York, haveinvented a new and useful Hydrometer Cup and Thief, of which. thefollowing is a specification.

My invention relates to a thief for taking fluid from a barrel inconjunction with a hy drometer and thermometer cup; and the ob-j jeet ofmy invention isto take fluid from a barrelby the use of a thief, fillthe hydrometercup, and'test the liquid by both hydrome ter andthermometer without removing the thief from the barrel; second, to keepa con tinuous stream of. liquor obtained from the center of the barrelgoing through the cup, so as to impart to the cup the same temperatureas the fluid in the barrel; third, toreturn the fluid to the barrelwithout waste. 1 attain these objects by the instrument illustrated inthe accompanying drawings, in which- Figure 1 is a vertical section.Fig. 2 is an elevation. Fig. 3 is a plan view of a cross section on theline X Y. Fig. 4 is a plan view of a cross-section of the hydrometerandthermometer cup A B on the line V W.

Similar letters refer to similar parts through, outthe several fviews.

The hydrometer-cup A, Figs. 1, 2, and 4, is of the usual pattern andkind most commonly used by gagers, having a thermometer-chamter-cup A isremoved, and the hollowcylinder or tube D is attached in a permanentmanner thereto by the cylindrical piece H, as shown at Fig. 1. Thecylindrical piece H also forms a seat for the valve G. The cylinder ortube Eis also attached in a permanent manner to the piece H, as shown atFig.1, which tube E is sh orter and smaller in diameter, and is placedinside the tube D, as shown at Figs. 1 and 3. A valve is also placedinside the lower end of the tube D, as shown at Fig. l, of which 0 isthe seat and Mthe valve. The seat and valve 0 M is large enough to fillthe entire diameter of the tube D at the bottom end. The valve M has inthe center a small chamber, as shown at N, Fig.1. The rod K connects thetwo valves G and M, as shown at Fig. 1. One end of the rod K is insertedinto the valve M loosely, the hole through the valve-disk M bean eyebetween the valve G and the button on ing larger in diameter than therod K, and on the end of the rod K, inside the chamber N of the valve M,is a button or nut, which plays 5 loosely up and down in the chamber Nand prevents the rod K from coming out of the valve M, as shown at K,Fig. 1. p The other end of the rod K passes through the valve G andprojects a short distance above, having on the end a button or nut, asshown at'K, Fig. 1. The valve G is rigidly fastened to the rod K, whichpasses through it, so that the rod K" cannot move without moving thevalve G, and the valve G rod K. v

I, Fig. 1, is a wire, having a handle above the chamber B, at T, passingdown through the chamber B and inclosing the rod K loosely by top of therod K, as shown.

thief-tube D, and the other end of the tube F enters an elastic hollowball or bulb, made of rubber, similar to those commonly used on at- 7omizers.

The parts marked P, Figs. 1 and 2, are projections or stops attached tothe side of the tube D,'which prevents the thief from sinking into thebarrel too far, and at the same time keeps the thief away from the edgesof the bun g-hole, thus allowing an overflow from the cup to cling tothe sides of the cup and thief and return to the inside of the barrelwithout waste.

The handle B is attached to the outside of 8 the front or thermometerchamber B of the cup, as shown at Fig. 2, and the front or thermometerchamber B is extended and raised higher than the hydrometer-chamber A ofthe cup, as shown at T, Figs. 1 and 2. To operate the instrument, insertthe tube D into the barrel whose contents are to be tested or. proveduntil the entrance of the thief is arrested or stopped by theprojections or stops P and the small tube F coming in contact with thebung-hole edge. The tube D being considerably smaller than thebung-hole, and the stops P and small tube F being at-[ tached at anangle to the tube D, as shown at Figs. 1 and 2, the tube D will be inthe cen-' 1 terof the bung-hole, with an annular space all around thetube D. By the action of droppingthe thief into the barrel, the valve M,being loose, allows the spirit or other fluid concannot move withoutmoving the F is a small tube,that enters the side of the tained in thebarrel to enter the tubes D and E up to the same height as the height ofthe liquid in the barrel. By squeezing the ball or bulb (lwith the handthe air in the bulb or ball is pressed downward and against the surfaceof the liquid that is in the annular space between the inside of thetube D and the sition on the seat 0.

outside of the tube E, which forces the liquid up through the tube E andvalve G E into the cup A B. By releasing the ball or bulb C aftersqueezing the ball again expands, causing a vacuum in the tube D, whichvacuum the liquid in the barrel rushes through the valve 0 M to fill.The liquid that has been forced into the cup A B is retained in itsplace by the closing of the valve G. By again squeezing the bulb G theoperation of forcing the fluid into the cup A B through the tube E isrepeated, and the operation is to be repeated until the cup A B is full.By having the valve M loose, with. room to play up and down on theconnecting-rod K, when the liquid enters the tubes D E through the valve0 M the valve-disk M will rise without disturbing the valve G, so whenthe fluid is forced through the valve H G into the cup the valve-disk Gwill rise to allow the passage of the fluid without raising thevalve-disk M from its po- Whenever desirable to give the cup the sametemperature as the liquid in the barrel, by continually squeezing andrelaxing the bulb any quantity of the fluid can be passed through andover the cup A, while by having the top part of the cup B at T raisedhigher than the part A, all the overflow will return to the barrel bycapillary at- By having the sides of the chamber B higher than the sidesof the adjacent chamberA all the overflow of liquid,

when forced from the barrel through the hydrometer-cup, takes place overthe sides of the cup A, thus returning directly to the barrel. If thesides of both chambers are of 'a uniform height, the overflow will benearly equal over the sides of each chamber, and a portion of theoverflow will be diverted by [the chamber B down the sides of thechamber B and flow over onto the outside of the barrel, and not returnthrough the bung-hole. By having the handle B placed on the side of thechamber B when the overflow takes place none of the liquid is divertedfrom a line with the bung-hole and obstructed in its passage to theinside of the barrel, as would be the case if the handle were placed onthe side of the chamber A. The thief and cup can remain in the barrelwhen the hydrometer is inserted, or can be lifted out of the barrel andheld up by the handle B, the closed valves G and- M retaining the liquorin the cup and thief. By raising the rod I by the handle at T it raisesthe valve G, and the valve G, having the rod K attached to the valve M,asbefore described, raises the valve M, thus emptying the cup and thiefthrough the bottom while lifting the instrument out of barrel. The loopor stop S prevents the rod I and valves G and M from being raised toohigh.

I am aware that prior to my invention hy-' drometer-cups have beencombined with a thief. Therefore I do not claim such a combination,broadly; but

What I do claim as my invention, and desire to secure by Letters Patent,is

1. A thief for raising liquids, consisting of an outer tube fitted onthebottom,with avalve,

O M, and an interior tube shorter and smaller I than the exterior tube,having the lower end open and the upper end fitted with and closed by avalve, G, a connecting-rod, K, between the valves G and O M, and alifting-rod, I, having a small projecting tube, F, with one end insertedinto the outer tube, D, and the other end inserted into an elastic ball,all sub- I stantfally for the purpose shown and described. 2. A thiefhaving an outer tube, D, fitted on the bottom, with avalve, O M, and aninterior 7 or inner tube fitted on the top, with a valve,

G, and a connecting-rod, K, from the valveG to the valve 0 M, alifting-rod, I, having an elastic ball connected to the outer or largetube, D, by asmall tube, F, and projections or stops I, substantially asshown and described.

3. Thecombination of a thief, substantially as shown and described, witha hydrometercup having a thermometer-chamber with its walls projectingabove the sides of the hydrometer-chamber, substantially as shown anddescribed. l V

4. A thief combined with a hydrometerchamber, and a thermometer-chamber,the walls of the latter chamber projecting, abovethe sides of thehydrometer-chamber, and a handle, R, affixed to the thermometer-chamber,substantially as shown and described.
